Description
Technical Field
[0001] The utility model relates to the field of injection molding, and particularly relates to a modular insert wire clamp forming die. Background Art
[0002] For a computer, there are various cables inside, and there are various wire cores inside these cables. Therefore, at the joints of these connections, each wire core needs to be fixed one by one through a wire clamp. As Figure 8 shown in the wire clamp, the wire clamp is provided with wire grooves for various specifications at both ends. The sizes of the individual wire grooves are different and all penetrate the wire clamp along the height direction of the wire clamp. Different types and specifications of wire cores are clamped and fixed through the wire grooves. For CABLE and HUB wire clamps, due to the large structural differences between the two types of cables, it is impossible to produce the two types of wire clamps with the same set of dies. Therefore, a set of dies needs to be equipped for each specification of wire clamp product. When changing the dies, it is necessary to disassemble and replace the dies, and the processes of die disassembly, die installation, and debugging are required. It takes 30 minutes to change a set of dies. This increases the number of dies and the die opening cost, the die management workload is large, and the die change time is long.
[0003] Moreover, due to the influence of the volume of the cable itself, the volume of the wire clamp itself is also small. The diameter of the ejector pin installed on the ejector pin panel is much larger than the body of the wire clamp product, making it difficult to eject and form the product.
[0004] Therefore, the purpose of the utility model is to provide a modular insert wire clamp forming die, which can realize the production of multiple wire clamps with one set of dies by replacing the upper die core and the lower die core while reusing the template, the ejecting mechanism, and the pouring mechanism, and at the same time ensure that the injection molded part can be successfully formed and ejected smoothly.
